California Hot Spots Program

Learn about the steps needed to find air toxics hot spots, assess related health risks, and reduce those risks.

A “hot spot” is an area where air toxics levels are higher than in the overall region. This is usually caused by emissions from a local facility.

The Air Toxics Hot Spots Program requires permitted industrial, commercial, and public facilities to report on the air toxics they release. High-priority facilities must prepare a Health Risk Assessment (HRA). If the HRA shows that health risks are high, the facility must notify individuals exposed to the air toxics and develop a plan to reduce these health risks.
